Earlier quoted context omitted.
It is a side-by-side comparison of OSM data from 2012 (left) and the current OSM data. In my local area the difference is massive: the 2012 data has some roads but that's about it, no buildings, house numbers, etc. That's all present on the 2022 version (disclaimer: partly because I spent several months walking around mapping things with the StreetComplete app [1]). For me it isn't down, just taking a very long time…
I can’t open it, but here it’s the opposite :( OSM used to be amazing, better than google, now it’s horribly outdated. It shows several stores in my street that have closed over 6 years ago. I actually found StreetComplete a few days ago and have started fixing issues, at least for my neighborhood.
And OSM is the only map that shows the new roundabouts near my house. I just put them in yesterday after riding my bicycle around them several times to get a track.
We are OSM! If it has shortcomings, we've no one to blame but ourselves.
